In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The network switching method and apparatus provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

As shown in fig. 1, an embodiment of the present application provides a network handover method, including:

step 102, acquiring a first evaluation value of voice quality during the process of communication through the first network.

In one embodiment, the first evaluation value includes: MOS value or packet loss rate.

In this embodiment, the first evaluation value may be selected as a MOS (Mean Opinion Score) value, where the MOS value is a general or Mean Opinion Score calculated for all audio files after taking a Score given by each listener, where the larger the MOS value, the better the voice quality, and vice versa, the smaller the MOS value, the worse the voice quality.

In this embodiment, the first evaluation value may select a packet loss ratio, where the packet loss ratio refers to a ratio of the number of lost data packets in the test to the number of transmitted data groups, and specifically, in this embodiment of the application, the packet loss ratio may be a ratio of the number of data packets received by the electronic device to the number of data packets transmitted by the base station to the electronic device in a preset time period during a call. The preset time period can be set according to actual use requirements, and is not described herein again.

In one embodiment, the first evaluation value is obtained periodically, that is, the first evaluation value of the voice quality is obtained periodically during the call through the first network, so as to realize the continuous monitoring of the voice quality during the call.

In a case where the first evaluation value is less than or equal to the first threshold value, a first duration for which the first evaluation value is less than or equal to the first threshold value is acquired, step 104.

In this embodiment, when the acquired first evaluation value is smaller than the first threshold, timing is started, and the magnitude relationship between the updated first evaluation value and the first threshold is determined, and if the updated first evaluation value is still smaller than the first threshold, an interval duration is accumulated, and in cycles, the accumulated duration is a duration, where the interval duration is a duration between two times of acquiring the first evaluation value.

And 106, switching the electronic equipment from the first network to the second network under the condition that the first duration is greater than or equal to the first duration.

In this embodiment, the first duration may be a value according to actual usage requirements, where the first duration is longer than the interval duration.

The first network is an NR network, and the second network is an LTE network.

Among them, NR, i.e. 5GNR, is a global 5G standard based on a new null design of OFDM (Orthogonal Frequency Division Multiplexing).

The Long Term Evolution (LTE) of The Universal Mobile Telecommunications technology is a Long Term Evolution based on The Universal Mobile Telecommunications System (Universal Mobile Telecommunications System) technical standard developed by The 3GPP (The 3rd Generation Partnership Project) organization.

In this embodiment, a first evaluation value of the voice quality during the call is obtained, so as to measure the quality of the voice quality during the call in the current network according to a comparison result between the first evaluation value and a first threshold, and further switch the network of the electronic device when the current voice quality is relatively poor. The voice quality during conversation is improved by switching the network of the electronic equipment, and the requirement of a user on the conversation quality is further met.

By acquiring the first evaluation value so as to continuously compare the first evaluation value with the first threshold value, and in the case where the first evaluation value is less than or equal to the first threshold value, acquiring a duration of the first evaluation value that is less than or equal to the first threshold value, that is, a first duration, and comparing the first duration with the first duration, thereby determining the situation of call quality for a period of time, in the case where the first duration is greater than the first duration, the network of the electronic device is switched from the first network to the second network.

In the above embodiment, the setting of the first duration can reduce the frequency of network switching, and ensure the conversation experience of the user.

In any of the above embodiments, the network handover method further includes: acquiring a call state of the electronic equipment; and when the call state is the call holding state, maintaining the network of the electronic equipment unchanged until the call is ended.

In the embodiment, the call state is acquired, and the network is kept unchanged according to the call state, so that the switching frequency of the network is reduced, and the influence of network switching on the call is reduced. Such as reducing the voice glitch at the moment of switching.

Illustratively, the network before switching is VoNR, the network after switching is Voice call under Long term Evolution Voice bearer (VoLTE), and in the process of subsequent call, the network of the electronic device is always maintained under the Voice call under the Long term Evolution Voice bearer.

In one embodiment, switching a network of an electronic device specifically includes: transmitting the network after performing the switching to the modem so that the modem operates according to the network after the switching; and in the case of receiving the confirmation information fed back by the modem, the network switching of the electronic equipment is ended.

In this embodiment, the network switching is realized by sending the switched network to the modem so that the modem can perform actions according to the switched network, and in this process, the network switching is ended by limiting the condition that the confirmation information fed back by the modem is received, so as to ensure that the network is switched.

step 210, switching the voice call under the VoNR to the voice call under the VoLTE;

step 212 is executed to determine whether or not the call is ended, and if not, step 212 is executed, and if yes, the call is ended.

In one embodiment, after the electronic device is switched from the second network to the first network, the method further includes:

updating the first evaluation value; controlling the network of the electronic device to switch between the first network and the second network according to the updated first evaluation value.

In any of the above embodiments, the second evaluation value is updated, and the second network is switched to the first network based on the updated second evaluation value, the second threshold, and the second duration, so that the network of the electronic device is switched between the first network and the second network until the call is ended.
